The methyl groups of the pyrroles Ia and IIa react with sulphuryl chloride to give dichloromethyl derivatives which hydrolyze to aldehydes. The pyrrole Ia also forms a trichloromethyl derivative which hydrolyzes to the corresponding acid. Alkaline decarboxylation of the latter gives opsopyrrole-dicarboxylic acid, IVa.
吡咯 Ia 和 IIa 的甲基与磺酰氯反应生成二氯甲基衍生物,该衍生物水解为醛。吡咯Ia还形成三氯甲基衍生物,其水解成相应的酸。后者的碱脱羧得到opsopyrrole-二羧酸,IVa。
